Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31478314, here are decompositions:

5 + 31478309 = 31478314
47 + 31478267 = 31478314
167 + 31478147 = 31478314
233 + 31478081 = 31478314
347 + 31477967 = 31478314
431 + 31477883 = 31478314
443 + 31477871 = 31478314
503 + 31477811 = 31478314

Showing the first eight; more decompositions exist.
